― Malfunction detection function: detects malfunctions of the input/output devices and system components of the ATX.
― Fail-safe function: controls the output device function and input value of the sensors/switches to ensure minimum vehicle drivability when a failure is detected.
― Memory function: stores the DTC when a failure is detected.
― PID data monitoring function: monitors the input/output signal and calculated value of the TCM and sends the monitoring data to the scan tool.
― Simulation function: Allows override operation of simulation items for input/output system parts preset in the TCM.
